Terminal welded and crimped to a wire and a shrinkable tube covering the wire and the terminal

Abstract

A terminal-provided wire ( 10 ) includes a wire ( 11 ) formed by covering a core ( 12 ) with an insulation coating ( 13 ), a terminal ( 20 ) to be connected to the core ( 12 ) exposed at an end of the wire ( 10 ), and a shrinkable tube ( 28 ) for sealing a wire connecting portion ( 25 ) formed by connecting the exposed core ( 11 ) and the terminal ( 20 ). An inclined surface ( 12 A) for making a thickness of the core ( 12 ) smaller toward the tip of the core ( 12 ) is formed by welding on a part of the exposed core ( 12 ) before the wire connecting portion ( 25 ).

The invention claimed is: 
     
       1. A terminal-provided wire, comprising:
 a terminal having a base extending in forward and backward directions and a wire connecting portion; 
 a wire having an end, a core extending from the end and an insulation coating covering the core from a location spaced from the end so that a section of the core from the end to the insulation coating defines an exposed core portion, an area of the insulation coating in proximity to the exposed core portion being crimped by the wire connecting portion to define a crimped connection between the terminal and the wire, the exposed core being welded to the base of the terminal to define a weld having an inclined surface extending from the end of the core to a position on the base of the terminal spaced from the wire; 
 and 
 a shrinkable tube fitted about the terminal and the wire, the shrinkable tube covering at least the inclined surface of the weld, the exposed core, and a portion of the insulation coating. 
 
     
     
       2. A terminal-provided wire according to  claim 1 , wherein the wire connecting portion is formed by welding. 
     
     
       3. The terminal-provided wire of  claim 1 , wherein the inclined surface is formed by welding. 
     
     
       4. The terminal-provided wire of  claim 1 , wherein the terminal comprises first and second crimping portions rearward of the wire connecting portion crimped to the insulation coating of the wire. 
     
     
       5. The terminal-provided wire of  claim 4 , wherein the shrinkable tube extends from a position forward of the inclined surface to a position rearward of the first and second crimping portions. 
     
     
       6. The terminal-provided wire of  claim 1 , wherein the core comprises a plurality of metal strands. 
     
     
       7. The terminal-provided wire of  claim 1 , wherein the shrinkable tube is heat-shrunk to the terminal and the wire. 
     
     
       8. The terminal-provided wire of  claim 1 , wherein the inclined surface of the core is forward of the wire connecting portion of the terminal.
